Application filed December 15, 1920. Serial No. 431,031.

T 0 all whom e't may concern Be it known that I, Gnoncn P. HAYNES, acitizen of the United States, residing at Brooklyn, in the county ofKings, State of New York, have invented a new and useful Valve, of whichthe following is a specification.

My invention consists of a novel construction of a valve, which isadapted for handling heavy viscous liquids that have a large amount ofsolid matter in suspension, which can be cheaply manufactured, isreadily accessible for the purposes of inspection, replacement orrepair, and has no packing boxes or glands, the valvular members beingself grinding and the valve being slow or quick operating and readilyoperated under high pressure by reason of my novel construction andcollocation of gearing common to the valve members, the valve casing andthe operating post.

To the above ends my novel invention consists of a novel construction ofa valve comprising top and bottom bonnets, an intermediate center ring,a plurality of valvular members provided with juxtaposed telescopingportions, one of said valvular members being provided with a pinion inmesh with an internal gear, cast or formed upon the center ring, saidpinion meshing with a driving gear carried by an operating post, whichis journaled in the bottom bonnet in a novel manner.

To the above ends, my invention Consists of a novel construction of avalve, the novel features of which will be hereinafter fully set forthand pointed out in the claims.

For the purpose f illustrating my invention, I have shown in theaccompanying drawings, forms thereof which are atpresent preferred byme, since they will give in practice satisfactory and reliable results,although it is to be understood that the various instrumentalities ofwhich my invention consists can. be variously arranged and organized andthat my invention is not imited to the precise arrangement andorganization of these instrumentalities as herein shown and described.

Figure 1 represents a vertical sectional view of a valve embodying myinvention.

Figure 2 represents a section on line 2-2 of Figure 1, certain of theparts being removed for clearness of illustration.

Similar numerals of reference indicate corresponding parts.

1 designates my novel construction of valve, the same comprising thecasing composed preferably of the top bonnet 2 and the bottom bonnet 3and the intermediate center ring l, the latter being held between thejuxtaposed outer faces of said bonnet members by means of the bolts orother fastening devices 5, which pass through the lugs 6 and T of saidbonnets and center ringrespectively. k

The top and bottom bonnets 2 and 3 are provided with the threadedaligning openings 8 and 9, which communicate with the enlarged annularchambers, 10 and 11, which communicate with the ports 12 and 13 of anydesired contour in said top and bottom bonnets respectively, either ofsaid ports being capable of serving as inlet or outlet ports.

The port 12 is provided with an inner valve seat 14 against whichcontacts the upper valvular member or loose disc: 15, which isprovidedwith the extension 16, which is contained in the pocket formedwithin the annular wall 17 of the lower valvular member 18, which coactswith the lower seat 19 around the lower port 13.

The telescoping arrangement of the parts 16 and 17 of the valvularmembers, ensures the proper relationship of the valves to each other andtheir coacting parts at all times.

20 designates a coil spring or other tension device located between thevalvular members 15 and 18 and tending to normally press said valvesoutwardly against their respective seats. On the walls 17 of the valvemember 18 are formed the gear teeth comprising the pinion or geared disc21, which engage the internal curved rack or series of gear teeth 22formed on the inner "face of the center ring 4, said pinion 21 being inmesh with the gear 23, which is formed on or secured to the oper tingpost 24 having the extension 25, which has the squared portion 26, uponwhich is fitted the operating handle 27 which is secured in position bythe pin 33 or the like. The outer shoulder 28 of the operating post 241is contained or guided in the seat 29, in which is contained theoperating post packing gasket 30, said gear 23 and its adjuncts beingheld in proper position by the operating post spring 31 one end of whichcontacts with the inner wall of the top bonnet 2, while its other end iscontained in the central seat 32 of said operating post.

In order to reduce the exterior dimensions of the valve casing andparticularly the center ring 4 to as small a compass as is practicable,I provide the eccentric internal recess 34 in said center ring, wherebysufficient clearance is provided for the teeth of the operating postgear 28.

The pitch of the teeth on the operating post gear 23 is slightly smallerthan the pitch on the pinionor geared disc 21, and the pitch of theteeth of said disc 21 is slightly smaller than the pitch of the teeth 22of the internal rack formed in the center ring 4:, whereby I ani'enabledto considerably reduce the overall dimensions of my novel valve, sinceif the same pitch was maintained throughout all of said three gearelements, the valve would have to be considerably larger in order forthe operating handle to open it full by the movement through an arc of180, the relative variations of pitch being indicated by the legends onFigure 2 and being clearly understood by those skilled in the art. 7

It will be apparent from the foregoing that in my novel construction ofvalve, there is created by the actuation of the valve disc, a rotatinggrinding motion upon the valve faces during the opening and closing ofthe valves.

The valvular members or discs never leave their respective valve faces,which minimizes the probability of any foreign substances gettingbetween said discs and their seats and the valve faces are swept clearof any foreign substance at each pass of the disc.

By arranging the inlet and outlet openings very close together anddirectly in alignment, the liquid that the valve is handling ispermitted to pass through the valve unobstructed or retarded in any wayand in my novel construction either of the valved openings can be usedas inlets or outlets or vice versa.

By the employment of the central separating ring, easy access ispermitted to both Valve facings for regrinding or refacing the same andI am further enabled to make the valve so that it is pressure tight fromeither side instead of in one direction, as is the usual practice invalves of this general character now in use.

By the employment of my novel system of gearing, wherein the drivinggear of the operating post meshes with the pinion formed on one of thevalve members, which pinion is in mesh with the rack cast or formed onthe center spacing ring, there is considerably increased leverage.provided to operate the valves which enables the valve members to bereadily actuated by a moderate pressure exerted on the operating handle,which is an important feature where the valves are used under a highpressure.

By providing a close clearance between the bonnets, I eliminate theliability of deposits of heavy foreign substances, within the valvecasing, and the scavenging effect caused by the rotation of the gearing,results in the breaking up and dislodging of any heavy foreignsubstances during the operation of 7 the valve and renders my novelconstruction particularly applicable for handling heavy viscous liquidsor liquids that have a large amount of solid matter in suspension.

By recessing the separating ring so as to receive the driving gear ofthe operating post, I am enabled to materially reduce the overalldimensions of the valve casing.

By making the pitch of the teeth on the operating post gear slightlysmaller than the pitch of the teeth on the geared disc or pinion of thevalvular member, which in turn is slightly smaller in pitch than theteeth cast on the center ring, I am enabled to get much better resultsthan if the pitch of said teeth were the same throughout, in which eventthe valve would have to be con siderably larger in order for theoperating handle to open it fully by a movement through an arc of 180.

By the provision of the telescoping, juxtaposed extensions of the valvemembers, with the spring between the latter, said valve members arealways pressed tightly against their respective seats and maintained inproper position with respect to each other.

By the provision of the spring abutting against the operating post, itsgear is al; ways retained in its proper relative position with respectto the valve pinion and the provision of the operating post packinggasket effectively prevents leakage, there being no packing boxes orglands necessaryin my construction and the valves are self grindingduring their normal operation.

It will now be apparent that I have devised a novel and useful valvewhich embodies the features of advantage enumerated as desirable in thestatement of the invention and the above description, and while 11 Ihave, in the present instance, shown and described a preferredembodiment thereof which will give in practice satisfactory and reliableresults, it is to be understood that such embodiment is susceptible ofmodification in various particulars without departing from the spirit orscope of the invention or sacrificing any of its advantages.
